SURGICAL MASK POSITIONING SYSTEM

BACKGROUND OF THE INVENTION
1
The present invention relates to a novel positioning
system for a surgical mask used during surgical procedure.
Certain surgical procedures require a patient to lie in
a prone position. For example, spinal surgery is typically under-
taken with an anesthetized patient in such prone position on a
surgery table.
It is most important that a uniform pressure be applied
over the patients face for such prone-position patients.
Reduction of tissue pressures on the forehead and chin of an
anesthetized prone-position patient eliminates the possibility of
damage to the eyes of the patient, for example, central retinol
1
artery occlusion "CRAO". In addition, the patient's head should
a
be maintained in a neutral forward position without significant
neck flexion, extension, lateral flexion, or rotation to permit
the application of spinal surgery maneuvers. In addition,
localized ischemia may occur to the chin and forehead area of the
patients head if pressure to those areas is not controlled.
Thus, the need for adjustment of the angle and height
of a surgical head support is most important.
In the past, many systems have been proposed to support
the head of a person in a supine or prone position. For example,
United States Patents 2,107,962 and 2,239,003 show pillow supports
and head rest with adjustable supporting legs.

CA 2976954 2017-08-21
United States Patent 6,023,801 describes a therapeutic
head rest for use during medical treatment which includes four
adjustable legs supporting a padded cradle.
United States Patents 4,504,050 and 5,165,137
illustrate head supports used during medical imaging procedures
1
that include angular rotation slotted angular supports as well as
4
adjustable legs for the support platform.
United States Patents 7,426,763, 8,261,385, and
8,549,683 teach surgical head supports utilizing a shell with a
2
cushion insert positioned above a mirrored surface. The mirrored
surface includes adjustable legs extending downwardly therefrom or
about the periphery of the mirror.
;
A product sold under the designation PRONE VIEW
utilizes a shell helmet for holding a cushion in which a plurality
of threaded member extend up from a mirror surface to engage
bosses or extensions of the protective helmet. This arrangement
allows the adjustment of the helmet shell, although the shell must
be lifted onto the extending legs to secure the same for use.
A positioning system for a surgical mask that includes
a positioning system that is accurate and easy to implement would
be a notable advance in the medical field of surgical procedures.

SUMMARY OF THE INVENTION
;
In accordance with the present invention a novel and
useful device for positioning a surgical mask above a surface is
herein provided.
1
The device of the present invention utilizes a
conventional surgical mask having at least one boss extending
therefrom. One or more adjustable support legs are also provided
in the present invention. Each support leg includes a first
threaded element having a connector fixing the same to the boss
extending from the surgical mask. The first threaded element may
be fixed by any known connectors such as, screws, lamps, and the
like. However, in certain cases the first threaded element may be
fixed to the boss extending from the surgical mask by the use of a
connector in the form of a mastic or glue. This type of connector
is especially advantageous when the boss extending from the
surgical mask comprises a hollow member.
The adjustable support leg also includes a second
threaded element which adapted for rotatable and threadingly
engages the first threaded element. The second threaded element
during such engagement is extendable or movable relative to the
first threaded element. In certain cases, the first threaded
element may take the form of a hollow internally threaded
configuration, while the second threaded element may take the form
of an externally threaded element. In any case, the second
threaded element is moveable relative to the first threaded

element by rotation or turning.
The adjustable support leg also is provided with a
1
1
rotatable handle. The rotatable handle is fixed to the second
1
threaded element for rotation or turning with the second threaded
1
element. The rotatable handle is provided with a body that may
include a curved outer surface. Also, a protuberance or
projection entails part of the rotatable handle and extends away
from the fixed second threaded member.

A mirror is also employed in the present invention and
= 10 is positioned adjacent the adjustable support leg. The mirror
possesses a perimeter, a reflective surface, and an orifice
1
therethrough which lies inwardly from the perimeter. The
protuberance of the rotatable handle is extendable into the mirror
orifice and is capable of rotation relative to the mirror in this
position.

The body of the rotatable handle remains at or above the
reflective surface of the mirror during rotation of the rotatable
1
handle body and protuberance. Rotation of the rotatable handle
causes movement of the second threaded member relative to the
surgical mask, essentially adjusting the position of the surgical
mask relative to the reflective surface of the mirror.
Again, a multiplicity of adjustable support legs may be
k
used with the device of the present invention each including the
1
elements of the adjustable support leg described above. In this
1

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
Various aspects of the present device will become
apparent for the following detailed description of the preferred
embodiments thereof. Such embodiments should be referenced to the
prior described drawings to fully understand. the device sought for
patenting.
The device of the present invention is shown in the
drawings by reference character 10., FIGS. 3-6. Referring to
FIGS. 1 and 2, it may be observed that prior art positioning
1
mechanisms for surgical mask 12, such as the PRONEVIEW product, is
shown. Prior art mask 12 is depicted in FIG. 2 as including a
soft foam liner or insert 14 and is supported above a mirror 16.
Mirror 16 lies above a surface 18 which may be the top portion of
a surgery table. A plurality of adjustable legs 20 fixed to
mirror 16 allow the movement of surgical mask 12 away from and
toward mirror 16. Surgical mask 12 also includes a plurality of
bosses 22 which engage adjustable legs 20. With reference to
adjustable leg 24, typical of the plurality of adjustable legs 20,
an upwardly projecting rotatable screw 26 engages a threaded cap
26 placed within boss 30. To operate the adjustment mechanism of
adjustable legs 20, surgical mask 12 must be lifted above mirror
16 and placed upon the projecting screws, such as screw 26, of
each adjustable leg 20 in order to allow the threaded caps, such
as cap 28 of adjustable leg 24, to engage each one of the
plurality of bosses 22. Directional arrows 32 and 34 indicate the

downward placement of surgical mask 12 on plurality of adjustable
1
legs 20 via plurality of bosses 22.
Looking now at FIG. 3, it may be observed that an
1
exemplary adjustable leg 36 of the present invention is depicted.
conventional surgical mask shell 38, shown partially in FIG. 3,
includes an extending boss 40 which is a hollow member of roughly
cylindrical shape. Adjustable leg 36 includes as one of its parts
a first threaded element 42 having an exterior ribbed surface 44
and a head 46. A thread 48, best shown in FIG. 4, lies within the
1
interior chamber 50 thereof. A connector in the form of a mastic
Layer 52 positions between rib surface 44 of element 42 and the
interior surface 54 of boss 40. Thus, first threaded element 42
is fixed to boss 40 in this regard. Of course after types of
connectors may be used to fix first threaded element 42, as
heretofore delineated.
In addition, adjustable leg 36 further possesses a
second threaded element 56. Second threaded element 56 is
provided with an externally threaded surface 58 which is capable
of threadingly and rotatably engaging internal threaded surface 48
of first threaded element 42. Of course, the relationship between
external threaded surface 58 and internal threaded surface 48 may
be reversed such that first threaded element 42 includes an
externally threaded surface while second threaded element 56 is
provided with an internally threaded surface. In any case, the
turning of second threaded element 56 moves the same relative to
9
CA 2976954 2017-08-21
;
1
first threaded element 42, boss 40, and mask 38 fixed thereto. A
bore 60 in second threaded element 56 may be employed to receive a
filler or cap that may be inserted into bore 60 through surgical
mask shell 38. An opening 62 through end portion 64 of second
threaded element 56 is intended to interact with rotatable handle
66, more fully described below. Rotatable handle 66 is also
provided for in adjustable leg 36.
Rotatable handle 66 includes a body portion 68 with a
rounded outer body portion 70. Handle 66 is also fashioned with a
?
protuberance or projection 72. A threaded passageway 74 through
body portion 68 of rotatable handle 66 is intended to accept a
threaded fastener 74 that engages openings 62 within end portion
64 of second threaded element 56. Opening 62 may also include an
internal thread. In any case, second threaded member 56 is
secured or fixed to handle 66 in this manner, such that rotation
1
of rotatable handle 66 also turns or rotates second threaded
element 56. It should be noted that the outer surface 76 of
rotatable handles 66 includes a plurality of recesses 78 to
facilitate the gripping of rotatable handle 66 by the user of
adjustable leg 36.
Positioning device 10, including adjustable leg 36, may,
also include an adjustable leg 78 which is constructed in a
similar manner to adjustable leg 36. In fact, all the legs 36,
78, 96 and 98 associated with surgical mask shell 38 may include
the same adjustment mechanism as that found with respect
CA 2976954 2017-08-21
(-
adjustable leg 36 prior described.
Referring now to FIG. 5, device 10 also utilizes a
mirror 80 having an upper reflective surface 82 and a perimeter
84. Mirror 80 is intended to lie above a surface 86 which may be
the upper portion of a medical or surgical table. Mirror 80 also
includes orifices 88, 90, 92, and 94, aligned with legs 36, 78, 96
and 98. As shown in FIG. 5, legs 96 and 98 associated with
surgical mask shell 38 are similarly constructed to adjustable
legs 36 and 78. That is to say, a protuberance such as
protuberance 72 of rotatable handle 66 of adjustable leg 36, is
found on adjustable legs 78, 96, and 98, associated with bosses
100, 102 and 104 of surgical mask shell 38.
In operation, FIG. 5, the user places surgical mask
shell 38 atop mirrors reflective surface 62 near orifices 88, 90,
92, and 94. Surgical mask 38 having adjustable legs 36, 78, 96,
and 98 rest atop reflective surface 82 of mirror 80. Surgical
mask shell 38 is then slid along reflective surface 82 of mirror
80 to allow protuberance 72 of adjustable leg 36 to engage orifice
88 according to directional arrow 106. Simultaneously,
protuberances similar to protuberance 72 associates with
adjustable legs 78, 96, and 98 engage orifices 90, 92, and 94,
respectively. Surgical mask shell 38 is then secure in place atop
mirror surface 82 apart from perimeter 84 of mirror 80. Such
positioning, as may be seen, takes place without lifting surgical
mask 38, and allows the perimeter 84 of mirror 82 extend outwardly
